Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33612940, here are decompositions:

29 + 33612911 = 33612940
41 + 33612899 = 33612940
71 + 33612869 = 33612940
233 + 33612707 = 33612940
239 + 33612701 = 33612940
269 + 33612671 = 33612940
359 + 33612581 = 33612940
503 + 33612437 = 33612940

Showing the first eight; more decompositions exist.
